I haven't heard much talk about Dwayne Stovall here. He's a liberty candidate, and might make a great replacement for Cornyn. If you haven't heard of him please check out his website : Dwayne Stovall for U.S. Senator | Texans For Stovall
Direct election of Senators by the "people" (17th Amendment) killed Federalism as the founders envisioned for our form of government.
The States lost their "vote" in the national government when Senators curried the favors of fickle voters and not the interests of the State Legislatures.
Any candidate for Senate should campaign on the repeal of the 17th Amendment and restore to the States their voice in national government.
Prohibition (18th Amendment) was a very bad idea, and it was repealed.
