Vegas US Senate Odds 2024

US Senate IconThe Democrats lost control in the US House of Representatives but still hold a slight edge in the Senate. There are several Senate seats up for grabs in 202r, but the current Vegas odds for Republicans to flip enough seats for a meaningful majority in the upper chamber are not favorable.

The next election cycle has the potential to change the course of US history. Below, we provide some helpful information concerning the Vegas US Senate Odds for 2024.

Is It Legal To Bet On US Senate Elections?

Although Las Vegas casinos regularly post odds on political election outcomes, they cannot legally accept wagers on politics or elections. In fact, no US state’s domestic sportsbooks are able to do so. Vegas election odds are created to attract attention to NV’s local sportsbook and casino operations so bettors will wager on their other lines and play games and slots on the casino floors. But you can still legally bet on elections online!

The best option for political bettors to wager on US Senate elections is with an offshore sportsbook operating over the Internet. Wagering with an overseas book is almost universally legal because most states have no laws against the activity, and there are no federal US gambling laws preventing legal access.

However, there is one state that has nominal laws against online betting: Washington. That said, we have yet to hear of any fines or arrests in WA for online betting, though gamblers who ignore regional laws do so at their own risk.

Were The 2020 Georgia Senate Runoff Elections Important?

The 2020 Georgia Senate runoff elections were extremely important. Republicans needed to win one of the two seats in order to maintain majority control over the Senate. Meanwhile, Democrats needed to win both Senate seats to take full control of the executive and legislative branches, which would allow them to make policy decisions with no opposition.

That turned out to be the case, as both Democratic candidates ended up winning close races. Still, both Democratic challengers were underdogs at all the top Vegas election betting sites, so if you'd had the foresight to predict what was an admittedly obvious outcome (and an outcome we touted as a sure thing before the GA runoffs), then you could have made some easy money.

Senate Runoff Elections Explained

Here, we present an example of how many Senate runoff elections work. Take note, however, that the majority of states do not follow this particular runoff election system and have their own individual mechanisms in place. Georgia is one of twelve states that follows this runoff method, and it's relevant because GA was the last state to require a Senate runoff to date.

Candidates A, B, and C appear on the ballot for a US Senate seat. Candidate A gets 40% of the vote, Candidate B gets 38% of the vote, and Candidate C gets the remaining 22% of the vote.

If this state followed a plurality voting system, the candidate with the highest percentage of votes, Candidate A in this example, wins. But in a runoff election system, this works differently.

In States with runoff election systems, a candidate needs a majority (50+%) of the vote to win. If no candidate gets a majority in the general election, the two candidates with the highest percentages of votes compete in a runoff election.

In the example above, Candidate A and Candidate B are the two candidates with the most votes. Since neither got 50%, they both advance to a runoff election where the electorate votes between those two candidates.

Senate Special Elections Explained

A senate special election, or a bye election, is simply a Senate election that happens outside of the normally scheduled Midterm and general elections. For example:

Senator A is one year into his six-year term and experiences health issues that cause him to retire before his term is up. Since the normal election is still five years away, a special election will be held to determine who will fill the vacated Senate seat.

In some cases, a special election happens relatively immediately, but in other cases, the state governor may appoint an interim Senator to fill the empty seat until the next scheduled Midterm or general election.
