"Eighteen percent of likely US voters think Trump will be impeached before serving his full term in office," a press release summarizing the poll said. "Seventeen percent felt that way in September, down from a high of 29 percent, when Rasmussen first asked this question in late December 2017."
Meanwhile, "46 percent of voters think the House hearing should be expanded to look at the involvement of Biden and his son Hunter in Ukrainian affairs. Forty-three percent disagree, while 11 percent are undecided."
House Democrats claim Trump pressed Ukraine President Volodymyr Zelensky to open a probe of the Bidens by withholding nearly $400 million in US military aid - a charge that Republicans deny because the aid was released several weeks after a July 25 request by Trump even though Ukraine never launched a Biden investigation.
Democrats have also blocked a Republican request to subpoena Hunter Biden to testify.
Joe Biden has publicly admitted that as vice president he threatened to withhold about $1 billion in US military aid unless Ukraine dismissed a prosecutor who was investigating a company that employed his son, Hunter.
The 46 percent who want Biden investigated tracks closely with Trump approval ratings in daily presidential approval polls by Rasmussen.
