U.S. Senate Seats Up for Reelection

[This blog post was updated on April 19, 2024]

Of the current 100 Senators, 48 are Democrats, 49 are Republicans, and 3 are Independents.

If we’ve learned anything from the 2022 elections, it’s that one senator can make a significant difference on some extremely consequential issues, especially if the party control of the Senate is close.

It’s never too early for reelection vision time. The time to start organizing is now.

There are a total of 535 Members of Congress. 100 serve in the U.S. Senate, and 435 serve in the U.S. House of Representatives.

Each state sends two Senators to represent their state in the U.S. Senate. In the Senate, the majority has the power to schedule when various bills come to the floor for voting, but a single Senator can slow legislation from coming to the floor for a vote.

Since debate in the Senate is not concluded until 60 Senators vote for a cloture motion to approve a bill for consideration, the majority must also coordinate with the minority party to set the rules for debate on legislation.

Under this system, legislation can be debated for one or two weeks on the Senate floor alone.

Senators serve a six-year term, and elections to the Senate are staggered over even years so that approximately 1/3 of the Senate is up for reelection during any election.

  1. To whom or what organization should I donate to have Rand Paul voted out as Senator? To whom or what organization do I donate to have Mitch McConnell voted out as Senator?

    1. Act Blue is supporting Democratic candidates. Donations to them can be used for any of the candidates you choose. Donating to the Democratic candidates that are running against these 2 senators is money well spent.+

  2. I am positive if that mob had broken into the Senate Chamber and had murdered or maimed some of those Republican cowards, the remainder would still have voted to acquit their Cult Leader Donald. It is too bad that so very few in this country know history. Most of Donald’s base don’t have an I.Q. above room temperature. As to history, many of those cult members don’t know how many stars are on our ‘Old Glory’. They don’t know how many stripes there are or what they stand for. As to history, ‘what goes around, comes around’. Just read the antics of Adolf Hitler. Hitler spit out so much vile hatred, that his base grew from day to day. When he had the German Congress torched, his followers cheered! Like our Senate, his followers were in the minority in January 1933. This did not stop him or the idiots that followed. 12 years later he shot himself and his beloved Germany lay in total ruin. It was then that the people realized what had happened and the only thing they could do was blame everyone else. I bet Donald’s Daddy had two to three copies of ‘Mein Kampf’ and read Donald diligently from it at bedtime! The parallel between Hitler’s antics and Donald’s antics are immense. Maybe Donald will do the same as Adolf?
