Do you know anything about the primaries? Candidates fight to be nominated for their Party. That means they attack their candidates, who are either fellow Republicans or Democrats. Once the candidate wins the nomination from his Party, he can then attack the cnadidate from the oppossing Party. Just keeping you updated on basic rules of democracy in the USA.
The way to win conservative votes is to attack leftists.
This headline almost makes it sound he endorses Wendy Davis over Abbott, if that is the case he should probably be in a different primary.
I do not know a lot about Tom Pauken but if all I know about him is attacks on Greg Abbott, then it makes me think maybe he is a McCain type who bashes those in his own party and not those in the other party.
Tom Pauken, show us how conservative you are instead of just attacking Abbott. That is the real way to win the primary without salting the ground you are trying to win.
