Tom,
The Dem that I voted for in the last election and will vote for again is far better on my key issues than the lying rino he unseated and that is trying to unseat him! My blue dude is supporting the same sex marriage amendment, he voted against gun control, and even though we have not had a major union issue he let the government shut down during budget issues and he spoke against excessive MEA contract threats.
I have some Republicans that bleed Republican. The only reason I vote for them is they have proven faithfulness to my drop dead stances and their opponents have not. However, there will be issues if they fail me on those stances.
Anybody that votes party line strictly to vote party line is not using the gray matter God gave them.
