Getting a solidly conservative Congress is the most important thing we can do.
If the GOP establishment, in their well-established tradition of snatching defeat out of the mouth of victory, nominates Myth (and if he doesn’t pull a McLame and lose an easy victory), a SOLIDLY conservative Congress can minimize the damage he does to our country. The Senate is of critical importance due to their role in confirming SCOTUS nominees.
In some of the states the primary is our only chance, but the big name radio conservatives just refrain from endorsing in primaries.
