These are the races I am aware of that are competitive. There may be others, but no recent polls available for the others that I could find.
MAGA Fortress Build:
Florida - Rubio
Arizona - Masters
Pennsylvania - Dr. Oz
Ohio - J.D. Vance [RINO Governor DeWine may win re-election]
New Hampshire - Bolduc [RINO Sununu is likely to win re-election as Gov]
All of these States are winnable and will help build the MAGA Fortress. The first three may end up with DeSantis, Lake, and Mastriano as Governors. AZ and PA wins would replace Dems. The last two look like strong MAGA to me along with Masters. Rubio and Dr. Oz look like RINOS to me, but better than Commies.
"Swing" States:
Georgia - Hershel Walker
Nevada - Laxalt
Wisconsin - Johnson
North Carolina - Budd
A sweep of these states and MAGA/Republicans definitely takover the Senate. The first two are strong MAGA and would replace a Dem. The other two may be RINOs, but if they win it does help.
Deep Red States:
Oklahoma - Lanford and Mullin appear to be Republicans. I think both seats are getting filled this go around due to a Special Election
Flip States:
Colorado - O'Dea
Connecticut - Levy
Washington - Smiley
Vermont - Malloy
I listed these in order of probability of actually flipping. Colorado peeps are tired of all the satanist BS coming out of Boulder/Denver; and Connecticut peeps appear to be really pissed off about the raping of their State by leftists turning all their towns into shitholes. Washington and Vermont are longshots, but get ready to harvest some salt if their Commies get tossed.
Are you able to drop ballots off all on Election Day even though they are mail-in?
Yes but its 55 miles each way
