Uhhhhh, no.

There are 133 House candidates with a certified election victory.

A quorum (majority of the body) is required to conduct business.

A majority of 133 is 67, not 68.

There are 67 elected Republicans. They DO NOT need Democrats for a quorum....

"...However, Democrats are prepared to deny the 68-member quorum required to conduct House business until successful power-sharing negotiations conclude with Republicans.”"
