It would be like if there were elections for seats in parliament but th PM wasn't also running. It isn't a presidential election..mid his term...but is an election for members of congress.
Essentially the reason it is a big deal is because whichever party has the most seats in congress controls it and pretty much determines what gets passed, etc. So, if there is a republican president and a republican congress than it is going to be much easier for the republican agenda through. Same deal if it is a democrat congress and president. However, if it is, for example, a republican president and a democratic controlled congress than things get more complicated/interesting for both sides..ie checks and balances.
My ballot was sent in last week
