Is Senator Patrick Toomey a Closet Liberal?

I have been examining if the new "Tea Party" supported candidates will make a Conscious Conservative difference once they enter office.  So far, I have examined Senators Ron Johnson,  Marco Rubio, Rand Paul, Mike Lee and Jim DeMint. 

But what about Patrick Toomey, the Senator from Pennsylvania?

Unlike many of the other Senators I have examined, Senator Toomey has served in the House of Representatives, which gives him a record to examine.  According to http://www.govtrack.us/, Senator Toomey is a "centrist Republican" who actually appears to lean slightly to the left compared to other Senators.  In this world of Spin Doctors and right is left, I looked at his record to see if there is a basis for this ranking.  A check of many of his votes on http://www.ontheissues.org/ reveals that he voted along standard Republican lines, leaning Conscious Conservative on economic issues like voting to support Free Trade and leaning Liberal/Socialist on social issues such as voting to ban same-sex marriage and supporting endless overseas wars.

   It appears that Pat Toomey will do little to lean the Senate in a Conscious Conservative direction on his own.  There may be some hope if he is influenced by others with a more Conscious Conservative bent.
