What was the effect of the Surpreme Court's ruling in Citizens United v. Federal Election Commission?

The Court's ruling effectively freed corporations and unions to spend money both on "electioneering communications" and to directly advocate for the election or defeat of candidates (although not to contribute directly to candidates or political parties).

the  seven  days  battles  were  a series of seven battles over seven  days from june 25 to july 1, 1862, near richmond, virginia,  during  the american civil war. the  seven  days ended with mcclellan's army in relative safety next to the james river, having suffered almost 16,000 casualtiesduring  the retreat.
