In the citizens united case, the supreme court ruled that

corporations could no longer pay for political advertisements.
limits on the money corporations could spend in politics were constitutional.
corporations could more freely pay for political advertisements.
hillary clinton did not have the right to run for president.

I believe the correct answer from the choices listed above is the second option. In the Citizens United case, the Supreme Court ruled that limits on the money corporations could spend in politics were constitutional.

Hope this answers the question. Have a nice day.

Currently, as of february 2016, an american traveling in france would be by the exchange rate. the weakness of the euro and the strength of the us dollar means that items in france cost less to an american than they otherwise would. of course, if this trend reverses and the us dollar weakens and the euro strengthens, such as was happening in early 2008, an american traveling in france would have an adverse experience because items would cost relatively more.
