He's leader of the Republican Party so, yes, he helped shepherd the whole deal. Why wasn't this going on during previous governorships? Why was Walker so vilified by the Unions? They came in from all over.
And Walker has much to be proud of his fight against the Union.
However, given his comments to the Tea Party about not fighting Republicans, his Pro-Abortion language he used to support is "Pro-Life" bill, he first walking away from the Right-To-Work fight, and then having to reverse course because the state party, in his words, could not keep it's members in line, his supposed reversal on Amnesty and an Open-Border, and finally, instead of taking a strong 10th-Amendment position on Gay Marriage, signaling defeat in Wisconsin on this issue.
Given this recent instability when it comes to the fidelity to conservative causes and policies, he is a distant 2nd to Cruz and his rock-solid fidelity to conservative causes, and policies.
CRUZ or LOSE!
Remind me of how many abortions Cruz has stopped? None.
Remind me of how Ted Cruz could stop the enforcement of Gay Marriage? Oh, again, nothing.
Besides, Walker has talked one way or another on immigration, that's to be watched but it wasn't direct legislation and at least he has a track record that is more than 2 years of what can be opportunistic talk.
Given this recent instability when it comes to the fidelity to conservative causes and policies, he is a distant 2nd to Cruz and his rock-solid fidelity to conservative causes, and policies.
Cruz can talk all he wants over basically a 2 year track record and no concrete accomplishments. Walker is 19% to 20% Cruz in Texas itself. So be content with your analysis.
