With Congress officially in recess until November, campaign season is in full swing and this fall brings no shortage of competition for control of the U.S. Senate.

Since Republicans need to net just six seats to regain the majority in the upper chamber, Senate races from Alaska to Colorado to New Hampshire command the attention of politicos, pundits and pollsters.

The New York Times, for example, currently gives Republicans a 59 percent chance of taking back the Senate.

Here’s a quick guide from The Daily Signal on the hopefuls campaigning to keep a seat,  oust the incumbent or win a brawl over an open seat in nine of the hot Senate races.

Michigan

Michigan has not had a Republican in the U.S. Senate for two decades. But with more than $21 million spent so far, this race could be the most expensive in state history. Republican candidate Terri Lynn Land so far has an advantage in outside spending.

Kentucky

If Republicans take back the Senate, the expectation is that Kentucky’s Mitch McConnell, now minority leader, would become  majority leader. But first he must get past Democratic challenger Alison Lundergan Grimes. Although Republican presidential candidates won Kentucky in 2008 and 2012, it leans Democratic at the local level. The state’s coal industry means energy could prove to be a decisive issue.
