I'm ready to predict that we take the Senate (and I haven't said that on FR until now). Although that's not a certainty, it's more likely than not that we get your tsunami. FR members can help a lot by voting, getting our friends to vote, and getting other patriotic neighbors to the polls, especially in the close races below.
We will pick up: Arkansas, Indiana, and North Dakota.
We are very likely to pick up: Illinois, Pennsylvania, West Virginia, and Wisconsin, barring massive Dem vote fraud.
We lead, barely, in: Colorado and Nevada. It's a contest between turnout and Dem vote fraud.
We trail, barely, in: California and Washington. Again, it's a contest between turnout and Dem vote fraud.
The Dems lead in: Connecticut, Delaware, Hawaii, Maryland, New York (both), Oregon, Vermont, although there are no reliable recent polls in the public domain for several of those races.
The four West Coast races; California, Colorado, Nevada and Washington; are close enough that turnout will decide them, and the tsunami on the East Coast favors the patriotic candidates, which should give us a boost in the West. I expect us to take at least two of them. As for the races where the Dems lead in public polls, I'm not willing to write them all off. It comes down to turnout, get out the vote, and poll watching. I've given the maximum legal amount in this election, including significant amounts to several of those Dem-leaning races. We'll see if we get a surprise pickup, particularly the NY special election, DE, or Oregon.
