Most recent polls have showed it close with either side slightly ahead. Averaging them out puts leave ahead. The remain camp seems worried.

Why doesn't our side do the same and slam Obama over all the promises he made about how his election meant we wouldn't "bully" the world and "impose our will" on other countries? He has behaved exactly the opposite way when it comes to things like dictating to Israel that they shouldn't build settlements in the West Bank or threatening retaliation against the UK if they decide to leave the EU.
Huge missed opportunity in the PR war, IMO. Someone has dropped the ball.
