The respondents are predictably biased by party affiliation - with 71% of Democrats thinking Trump more likely colluded and 73% of GOP voters thinking Clinton colluded. 

Let's review the Clinton campaign's ties to Russia (and imagine if this were Trump's team):

Individuals connected to the Uranium One deal, in which Russia purchased the rights to mine 20% of American uranium, reportedly donated $145 million to the Clinton foundation before the deal was approved while Clinton was Secretary of State. 

Bill Clinton picked up a cool $500,000 for one Moscow speech. During the same trip he hung out with Russian President Vladimir Putin at his house. 

Hillary Clinton's Chief of Staff, John Podesta (who would have likely become her Secretary of State), sat on the board of Massachusetts energy company Joule Unlimited, along with senior Russian official Anatoly Chubais and Russian oligarch Ruben Vardanyan – who was appointed by Vladimir Putin to the Russian economic council. Two months after Podesta joined the board, Joule managed to raise $35 million from Putin's Kremlin-backed investment fund Rusnano.

(We're not even to the dossier yet)

Not only did John Podesta fail to properly disclose this relationship before joining the Clinton Campaign, he transferred 75,000 shares of Joule to his daughter through a shell company using her address. Despite the Russian assistance, the Daily Caller reports that Joule Unlimited folded shortly after Hillary Clinton lost the 2016 election.
