Past Republican Congressional victories have given a boost to merger and acquisition activity and the current political change could mean more of the same, according to several industry experts. Historically, there has been an uptick in M&A activity and deal value after Republicans have gained control of either the House or Senate. If you compare deal volume for 2002 (7,413) and 2003 (7,414) there is only a slight increase, but the value of the deals increased from $472,061 million to $572,516 million in 2003, according to data pulled by Dealogic.
