Like other VP choices in the past Ryan will also run for reelection i.e. Lieberman and Biden. But I think the Dems should actually make him work for it. Lieberman and Biden were shoe-ins to win reelection running statewide in solid blue states. Ryan's district went for Obama in 2008 and has a Cook PVI of only R+1 making it a swing district. The only reason why Ryan always wins my a large margin is because he has represented it forever. The Dem candidate should go hard on him. That way Ryan would have to debate him and spend precious time campaigning there taking away the time he has to criss cross around the US as the VP canidate.
