Web Validation last two errors need help democracy plugin

I have been validating my website and have two erros left and need help. They both have to do with democracy plugin/widget. Here is my site. And here is the validation . It says:

Error Line 138 column 44: general entity “dem_poll_id” not defined and no default entity.

… <a href=’/?dem_add_user_answer=true&dem_poll_id=1′ rel=’nofollow’ onclick=’r

This is usually a cascading error caused by a an undefined entity reference or use of an unencoded ampersand (&) in an URL or body text. See the previous message for further details.

and

Error Line 138 column 55: reference to entity “dem_poll_id” for which no system identifier could be generated.

…?dem_add_user_answer=true&dem_poll_id=1′ rel=’nofollow’ onclick=’return dem_a

This is usually a cascading error caused by a an undefined entity reference or use of an unencoded ampersand (&) in an URL or body text. See the previous message for further details.

I have no clue where the files are. Can someone help?
