While Theresa May believes that the main issue for the June 8th election is Brexit, but some opposition parties disagree. The Labour Party under Jeremy Corbyn "wants to talk about anything else." The Liberal Democrats' leader Tim Faron hopes to garner the 48% of voters who voted Remain in the referendum and win more seats in Parliament.
In general, the British voters have not changed much on their position on Brexit, and even Labour-leaning think tanks have found a vast majority of voters accept Brexit. So then what will be the main issues? Labour wants to focus on the economy, inequality, austerity, and public-spending cuts. The Torres want to make security an issue. UKIP wants to ban the burqa and sharia law, having won the Brexit vote but having difficulty finding its role.
If May is solely focused on Brexit, that could hurt her. The economy slowing, education cuts are rising, social welfare is fraying, etc. The article states, "...it sometimes seems as if Mrs May’s response to any policy concern, including Brexit, has reverted to a single answer: strong leadership." Luckily for May, more voters trust May due to this than any other party leader. Ultimately, her agenda is "whom they would rather have running Brexit talks and everything else." Because she knows she beats out her opposition, she can remain vague.
"Theresa May claims this is a Brexit election. It isn't."
