The limits are reasonable as is, and those pushing to change them should be ashamed. 
As to campaign limits for out of state donors,  I don't want people from Outside picking my representative for me. I live here, I've met my local politicians, I've looked at their voting records, and the consequences of their votes affect me, my community, and my state.  Their out of state relatives should spend their campaign donations on candidates where they live and will have to deal with the consequences.
If you want a shot at hearing a lesser known candidate's ideas, then don't make it so the better funded candidate can afford to buy all the air time.
