Why does the Libertarian poll so high here?
Because IN-09ers are tired of the seeing the same "Baron Hill supports violent video games, pornography, gay marriage, and stem cell research" ads every two years.
Depending on who is elected POTUS and how that individual governs, Hill could be either very vulnerable or just normally vulnerable. If Obama has a Clintonesque first two years, Sodrel could win in 2010. After that, he'll be favored in 2012 because of redistricting (which the GOP will likely control).
To get there, he must avoid being shellacked this time.
