U.S. Representative Tim Johnson is one of the most independent members of Congress, according to a new voting analysis.  The "Politico" analysis shows the six-term Republican from Urbana has voted against the party line 38-point four percent of the time in the 112th Congress.  Only three others, including Republican presidential candidate Ron Paul, voted against his or her party more often.  Johnson said in a news release that he thinks quote, "voters want someone who can think for themselves and is not a slave to party politics all of the time."  Johnson founded the Center Aisle Caucus in 2005 in an attempt to get elected leaders from both major parties to work together more often.
