Mana holds the ace card and can afford to set bottom lines for any deal with the Internet Party and has. Dotcom wasted no time last week in saying he is committed to getting rid of John Key.
Harawira was reinforcing that bottom line it yesterday, in case the other MP is Peter Dunne.
Dunne is an obvious suspect but not for defecting to the Internet Party.
That makes no sense.
But he is the obvious suspect for someone whom Dotcom could have approached about an alliance similar to the one he is proposing with Mana, someone with an electorate seat and a party who could help the Internet into Parliament and help themselves in the process to get more MPs.
Dunne has denied being Dotcom's "other MP" but that doesn't help. According to Dotcom, in his round of interviews last week, the MP has batted away media inquiries. So unfortunately for them, only the MPs who have denied it are suspects.
Dunne admits to having been in email contact with Dotcom in the past year.
Dunne said he had not met Dotcom which is believable.
He also told the Herald on Sunday "unless I am totally deluded, I can rule out any deal."
That could be interpreted in many ways, depending on whether you believe he is deluded or whether you believe Dotcom is deluded.
Dunne's record is not on his side either. At the time of Dunne's denials about leaking the Kitteridge report into the GCSB, the Herald DigiPoll showed that only 22 per cent of people believed his denial, 59 per cent thought he had leaked the report and 18 per cent didn't know.
If Dotcom contacted Peter Dunne now, I doubt he would have much truck with him. He is back in John Key's good books, and on Breakfast TV this morning, Key went as far as encouraging people to vote for Dunne's United Future, Act or the Maori Party - "all of the parties we pretty much know are coming with us'" he said.
But last year things were very different. Dunne was feeling unloved after being sacked as a minister under suspicion of leaking the GCSB report (prompted by illegally spying on Dotcom) and having his party deregistered. They may have had a lot to discuss.
All this is not to say that Peter Dunne had a discussion or reached any agreement with Dotcom at a bleaker time.
But you could hardly blame Hone Harawira for suspecting it.
And you could hardly blame Dotcom if he had sought him out.
