What we know
His biggest campaign financer in the last few campaigns has been sancorp; a $30 billion natural gas company. Presumably that would mean he is pro-natural gas and fracking etc.
In May of 2013 he drafted and was the main sponser of an education reform bill that increased funding to charter schools, school choice vouchers and required performance standards for teachers. This bill caused the largest teachers strike in history.
While his education plan was clearly anti-union, the only reason he was able to negotiate with the unions was due to his 20 years of helping unions in negotiations. From that we cab probably assume he opposes Right-to-work (if if he threw it onto teachers)
The other major legislation that he sponsored that year was the Delaware Watershed Act. Which added some environmental regulations and created some jobs. We're not given too much information on the bill other then that 2 democrats vote against it because it doesn't add enough regulations and that republicans oppose it cause it cracks down too much on oil companies.
While it isn't public news, his wife has had 3 abortions, I don't take Frank to be a hypocrite so this would mean he is pro-choice.
Contains spoilers for season 2:
In January of 2014, shortly before a government shutdown that would begin on February 1st, Frank makes deal with the republicans that raised the retirement age to 68, that included spending cuts to Medicare and other cuts suggested by the Tea Party (I'm really not sure why Curtis aka Ted Cruz and the tea party opposed such a bill). His proposed entitlement reforms would, according to the CBO keep social security solvent until 2055.
After a power outage, Frank tries to convince Walker to sign an executive order that would nationalize two of Tusks nuclear plants. While his reason for suggesting this was because of an influence war going on between him and tus k, allowing the president to nationalize energy companies on a wim would set dangerous precedent.
Overall there seems to be a lot of mix between democrat and republican views for Frank. Assuming he actually agrees with half of the views listed above. We know many if not most of these were less about getting good laws passed and more about increasing his own power and influence.
Assuming we don't know about all the backroom deals (which the American populous wouldn't) I would certainly vote Walker for reelection, the education bill he got through in the first hundred days of the job and his success at entitlement reform is, in my opinion, a better resume then anything any other president has done recently.
To me, the only major issue that Walker hasn't successfully tackled yet is government surveillance, and as of right now Walker has been the second greatest president of the last 100 years (behind good ol silent cal).
As of 6 episodes into the second season, I'd certainly be backing Walker-Underwood 2016
